Yeah, but it'd take less effort and time, right? Easy-peasy.
Mom and dad will realize that torching houses is good and will learn, and then carry on in the example you set. I'm sure the children whose toys you incinerated won't be plotting their revenge or nothing...
Well, I don't want to have to talk a prosecutor about why I committed arson. Nor do I want to have to explain to God why I participated in the annihilation of an entire segment of His creation.
But yes, if I did that, I wouldn't have to smell all the reasons inside the house that people have roaches, wouldn't have to have them fall on me, and no re-treats.
